Question

What is electronic configuration

Answer 1

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.

Answer 2

As we know the formula for arranging the electrons in the electronic configuration.

=> 2n² .

And the names of the cells are K, L, M, N and so on .

So ,

In K = 2n² = 2(1)² = 2

In L = 2n² = 2(2)² = 8

In M = 2n² = 2(3)² = 18

In N = 2n² = 2(4)² = 32

In 0 = 2n² = 2(5)² = 50


So the electronic configuration of the element Having atomic number 100, is = 1 .

And the valency = 1

Valency = Number of Valence electrons in an element.
